Re: AR12741 at it's full opening in H-a and CaK high resolution with C11 and C8 scopes.

Astonishing imaging, Valery.

Look at the details in the light bridge! You give adaptive optics a run for its money.
I can’t believe you were able to stack 3000 / 4000 frames! Were these “real time” quality selected by SSM?

Cheers.

Re: Close to AR2741

Beautiful shots, Maurits.

I love inverted disk views. I don’t know whether it’s psychological but they seem to reveal more detail.

Cheers.

Re: May 15 H alpha and May 10 CaK

Thanks everyone. Here I thought the gods of meteorology were just picking on me! A hazard of the hobby, clearly! (Hmmm....”clearly”...) Bart: I’ve been very lazy about recording my exposure settings lately. The CaK shots are probably around 5ms. I try to keep it as short as possible without boosting...

Re: Thursdays Hazy Start to the Day - 16th May

Nice shots, Mark. They do stand up well under magnification.
@RodAstro: I wonder if a little haze is beneficial. It does seem to be associated with less turbulence. In the end, though, I guess there is some sacrifice of fine detail.
Cheers.

May 15 H alpha and May 10 CaK

Hi Everyone. I should have paid more attention to the weather forecast. The day began with beautiful clear skies (not a cloud in sight) so I began the process of gearing up for an imaging session. I set up the C8 scope and, as the Daystar came to temperature and the Sun cleared the neighbour's tree,...

I like your idea of showing the increased exposure image to reveal structures in the spot.

Wow, the H alpha closeups are terrific, Alexandra.
The double stacking really produces a nice result.
Hope your little Grasshopper returns home soon!

Lots of detail in the closeup even though it’s “only” 120mm aperture!

Re: May 12th Spots and Proms

Terrific set!
I have to remember to be smarter next time and capture some continuum images while the Daystar is heating up.
(I’m assuming that’s how you took the first image.)
Cheers.

Re: May 10: AR2740 / 2741 in H alpha

Thank you Mark, Marty and Valery. Valery; You've identified the top two items on my "to do" list! Double stacking the Daystar and the Lunt LS50Ha etalon has proven to be challenging. Putting these both in a f/46 telecentric beam still gives me interference fringes (2-3) across the fov, no matter how...

Thank you Franco, Eric and Brian.

Brian, I hope your fields are drying up a little. It's disconcerting to read about the flooding going on in Ontario.
